onsenui and jaydata doesn't coexist

when using this order :

<script src="lib/angular/angular.js"></script>
<script src="lib/onsen/js/onsenui.js"></script>
<script src="http://include.jaydata.org/datajs-1.0.3.js"></script>
<script src="http://include.jaydata.org/jaydata.js"></script>
<script src="http://include.jaydata.org/jaydatamodules/angular.js"></script>

I get this error

TypeError: Class.extend is not a function  
    at Object.<anonymous> (onsenui.js:13049)  
    at Object.invoke (angular.js:4535)  
    at Object.enforcedReturnValue [as $get] (angular.js:4387)  
    at Object.invoke (angular.js:4535)  
    at angular.js:4352  
    at getService (angular.js:4494)

    at Object.enforcedReturnValue [as $get] (angular.js:4387)  
    at Object.invoke (angular.js:4535)  
    at angular.js:4352

And when using this order:

<script src="lib/angular/angular.js"></script>
<script src="http://include.jaydata.org/datajs-1.0.3.js"></script>
<script src="http://include.jaydata.org/jaydata.js"></script>
<script src="http://include.jaydata.org/jaydatamodules/angular.js"></script>
<script src="lib/onsen/js/onsenui.js"></script>

note: edited to correct the order

jaydata.js:3342 Uncaught TypeError: Cannot read property 'apply' of undefined

any help is appreciated!

Finally I found a solution based on Ilia Yatchev answer so thanks to him.

first I used the downloaded jaydata files instead of the online files since it contains the code change that Ilia Yatchev mentionned on his answer

var Class;
$data.Class = Class = new ClassEngineBase();

note : the order isn't a problem now

<script src="scripts/platformOverrides.js"></script>
<script src="lib/angular/angular.js"></script>
<script src="lib/onsen/js/onsenui.js"></script>
<script src="lib/datajs-1.0.3.js"></script>
<script src="lib/jaydata.js"></script>
<script src="lib/jaydatamodules/angular.js"></script>

then in the code we save a reference of the created entity:

var Todo = $data.Entity.extend("Todo", {
    Id: { type: "int", key: true, computed: true },
    Task: { type: String, required: true, maxLength: 200 },
    DueDate: { type: Date },
    Completed: { type: Boolean }
});

and we save a reference of the created context:

var TodoDatabase = $data.EntityContext.extend("TodoDatabase", {
    Todos: { type: $data.EntitySet, elementType: Todo }
});

then we can safely work these references:

var todoDB = new TodoDatabase("MyTodoDatase");
todoDB.onReady(function() {
    var tasks = todoDB.Todos.addMany([
        { Task: 'Step0: Get this this list', Completed: true },
        { Task: 'Step1: Define your data model'},
        { Task: 'Step2: Initialize data storage'}
    ]);
    todoDB.saveChanges(function() {
        tasks.forEach( function(todo) { alert(todo.Id) });
    });
});

if I don't save reference to the entity and the context I get this error
